## The job by hand

Bills arrive by email and post, duplicates slip through, and the due-date surprise is a month-end tradition nobody wants.

## The ask

> Hello, process these new bills and invoices

## What comes back

A Google Sheet lands in the `Bookkeepers Bills & Invoices Workspace` folder in your Google Drive: Vendor, Invoice, Amount, Due date, Duplicate check and Review status.

## What it takes over

1.  Reads the exact inputs and sources you approve.
2.  Saves the work as a review-ready Google Sheet in the Bookkeepers Bills & Invoices Workspace folder in Google Drive.
3.  Shows evidence, unknowns and blocks instead of guessing.
4.  Prepares the next action and stops at the human gate.

## How buying works

1.  Buy once for $19. Three files arrive: `skill.md`, `setup-prompt.txt` and `usage-prompt.txt`.
2.  Hand the files to the assistant you already use. It sets the job up on Google, Microsoft or Zoho and tests it on fictional data.
3.  Approve the setup. It runs the job and stops at every external action for your sign-off.

## Where it stops

It does not send, spend, publish, schedule or make a human decision without the exact approval that action needs.

## Common questions

### What does the queue contain?

### How does duplicate detection work?

It compares new items against recorded bills on vendor, invoice number and amount, and flags suspects for your call.
